WRG ASBESTOS PI TRUST DISTRIBUTION PROCEDURES The WRG Asbestos PI Trust Distribution Procedures (the "TDP") contained herein provide for resolving all "Asbestos PI Claims" as defined in the First Amended Joint Plan of Reorganization Under C,hapter 11 of the Bankr!lptcy Code cifw.r Grace & Co., et al., the Official Committee of Asbestos Personal Injury Claimants, the Asbestos PI Future Claimants' Representative, and the Official Conunittee of Equity Security Holders, dated as of February 27, 2009 (as it may be amended or ~edified, the "Plan"), 1 including, without limitation, all asbestos-related personal injury and death claims caused by conduct of, and/or exposure to products for which, W.R. Grace & Co. and/or the other Debtors (collectively referred to as "Grace"), and their predecessors, successors, and assigns, have legal responsibility as provided in and required by the Plan and the WRG Asbestos PI Trust Agreement (the "PI Trust Agreement"). The Plan and PI Trust Agreement establish the WRG Asbestos PI Trust (the "PI Trust"). The Trustees of the PI Trust (the "Trustees") shall implement and administer this TD? in accordance with the PI Trust Agreement. SECTION 1 Introduction 1.1 Purpose. This IDP has been adopted pursuant to the PI Trust Agreement. It is designed to provide fair, equitable and substantially similar treatment for all PI Trust Claims that may presently exist or may arise in the future. 1 Capitalized tenns used herein and not otherwise defined shall have the meanings assigned to them in the Plan and the PI Tru.st Agreement; provided, however, that "Asbestos PI Claims" as defined in the Plan shall be referred to herein as "PI Trust Claims." JA 200291

1.2 Interpretation. Except as may otherwise be provided below, nothing in this TDP shall be deemed to create a substantive right for any claimant. The rights and benefits provided herein to holders ofpi Trust Claims shall vest in such holders as of the Effective Date. SECTION2 Overview 2.1 PI Trust Goals. The goal of the PI Trust is to treat all claimants equitably. This 1DP furthers that goal by. setting forth procedures for processing and paying Grace's several share ofthe unpaid portion of the value of asbestos personal injury claims generally on an impartial, first-in-first-out ("FIFO") basis, with the intention of paying all claimants over time as equivalent a share as possible of the value of their claims based on historical values for substantially similar claims in the tort system? To this end, the IDP establishes a schedule of eight asbestos-related diseases ("Disease Levels"), seven of which have presumptive medical and exposure requirements ("MedicaUExposure Criteria") and specific liquidated values ("Scheduled Values"), and seven of which have anticipated average values ("Average Values") and caps on their liquidated values ("Maximum Values"). The Disease Levels, Medical/Exposure Criteria, Scheduled Values, Average Values and Maximum Values, which are set forth in Sections 5.3 and 5.4 below, have all been selected and derived with the intention of achieving a fair allocation of the PI Trust funds as among claimantl) suffering from different disease processes ij?-light of the best available infonnation considering the settlement histories of Grace.and the rights claimants would have in the tort system absent the bankruptcy... 2 As used in this TDP, the phrase "in the tort system" shall not include claims asserted against a trust established for the benefit of asbestos personal injury claimants pursuant to section 524(g) and/or section 105 of the Bankruptcy Code or any other applicable law. 2 JA 200292

2.2 Claims Liquidation Procedures. PI Trust Claims shall be processed based on their place in the FIFO Processing Queue to be established pursuant to Section S.I(a) below. The PI Trust shall take all reasonable steps to resolve PI-Trust Claims as efficiently and expeditiously as possible at each stage of claims processing and arbitration, whlch steps may include, in the PI Trust's sole discretion, conducting settlement discussions with claimants' representatives with respect to more than one claim at a time, provided that the claimants' respective positions in the FIFO Processing Queue are maintained and each claim is individually evaluated pursuant to the valuation factors set forth in Section 5.3(b)(2) below. The PI Trust shall also make every effort to resolve each year at least that nmnber of PI Trust Claims required to exhaust the Maximum Annual Payment and the Maximum Available Payment for Category A and.category B claims, as those terms are defined below. The PI Trust shall liquidate all PI Trust Claims except Foreign Claims (as defined below) that meet the presmnptive Medical/Exposure Criteria of Disease Levels I-V, VII and Vlll under the Expedited Review Process described in Section 5.3(a) below. Claims involving Disease Levels I-V, VII and VIII that do not meet the preswnptive Medical/Exposure Criteria for the relevant Disease Level may undergo the Pl Trust's lndividualreview Process described in Section 5.3(b) below. In such a case, notwithstanding that the claim does not meet the presumptive Medical/Exposure Crit.,ma for the relevant Disease Level, the PI Trust can offer the claimant an amount up to the Scheduled Value oftbat Disease Level if the PI Trust is satisfied that the claimant has presented a claini that would be cognizable and valid in the tort system. Claimants holding claims involving Disease Levels II-VDI may alternatively seek to establish a liquidated value for the claim that is greater than its Scheduled Value by electing the.pi Trust's Individual Review Process. However, the liquidated value of a claim that undergoes 3 JA 200293

the Individual Review Process for valuation purposes may be determined to be less than the Scheduled Value for the applicable Disease Level, and in any event shall not exceed the Maximwn Value for the relevant Disease Level set forth in Section 5.3(b)(3) below, unless the claim qualifies as an Extraordinary Claim as defined in Section 5.4{a) below, in which case its liquidated value cannot exceed the maximum extraordinary value specified in Section 5.4(a) for such claims. Level VI (Lung Cancer 2) claims and all Foreign Claims may be liquidated only pursuant to the Pl Trust's Individual Review Process. Based upon Grace's claims settlement histories in light of applicable tort law, and current projections of present and future unliquidated claims, the Scheduled Values and Maximllll) Values set forfu in Section 5.3(b)(3) have been established for each of the Disease Levels that are eligible for Individual Review of their liquidated values, with the expectation that the combination of settlements at the Scheduled Values and those resulting from the Individual Review Process should result in the Average Values also set forth in that provision. All unresolved disputes over a claimant's medicai condition, exposure history and/or the liquidated value of the claim shall be subject to bin!1ing or non-binding arbitration as set forth in Section 5.10 below, at the election of the claimant, under the ADR Procedures that are provided in Attaclunent A hereto. 3 PI Trust Claims that are the subject of a dispute with the PI Trust that cannot be resolved by non-binding arbitration may enter the tort system as provided in Sections 5.11 and 7.6 below. However, if and when a claimant obtains a judgment in the tort system, the judgment shall be payable (subject ~o the Payment Percentage, Maximum Available Paymerit, and Claims Payment Ratio provisions set forth below) as provided in Section 7. 7 below. 3 Attachment A will be developed by the Trustees with the consent of the T AC and the FCR, and will be included with this document when completed. 4 JA 200294

2.3 Application of the Payment Percentage. After the liquidated value of a PI Trust Claim other than a claim involving Other Asbestos Disease (Disease Level I - Cash Discount Payment), as defined in Section 5.3(a)(3) below, is detennined pursuant to the procedures set forth herein for Expedited Review. Individual Review, arbitration, or litigation in the tort system, the claimant shall ultimately receive a pro-mta share of that value based on a Payment Percentage described in Section 4.2 below. The Payment Percentage shalt also apply to all Pre Petition Liquidated Claims as provided in Section 5.2 below and to all sequencing adjustments paid pursuant to Section 7.5 below. An Initial Payment Percentage shall be set pursuant to Section 4.2 below promptly after the PI Trust is established by the Trustees after consultation with the PI Trust Advisory Committee (the ''TAC'') and the Legal Representative for Future Claimants (the "Futures Representative") (who are described in Section 3.1 below). The Initial Payment Percentage shall apply to all PI Trust Voting Ciaims accepted as valid by the PI Trust, unless adjusted by the PI Trust with the consent of the TAC and the Futures Representative pursuant to Section 4.2 below, and except as provided in Section 4.3 below with respect to supplemental payments in the event the Initial Payment Percentage is changed. The term "PI Trust Voting Claims" includes (i) Pre--Petition Liquidated Claims as defined in Section 5.2(a) below; (ii) claims filed against Gmce in the tort system or actually submitted to Grace pursuant to an administrative settlement agreement prior to the Petition Date of April2, 2001; and (iii) all asbestos claims filed against another defendant in the tort system prior to February 27, 2009, the date the Plan was filed with the Bankruptcy Court (the "Plan Filing Date"); provided, however, that (1) the holder of a claim described in subsection (i), (ii) or (iii) above, or his or her authorized agent, actually voted to accept or reject the Plan pursuant to the voting procedures established by the Bankruptcy Court, 5 JA 200295

unless such holder certifies to the satisfaction of the Trustees that he or she was prevented from voting in this proceeding as a result of circmnstances resulting in a state of emergency affecting, as the case may be, the holder's residence, principal place of business or legal representati'(e's place of business at which the holder or his or her legal representative receives notice and/or maintains material records relating to his or her PI Trust Voting Claim; and provided further that (2) the claim was subsequently filed with the PI Trust pursuant to Section 6.1 below by the Initial Claims Filing Date defined in Section S.l(a) below. The Initial Payment Percentage shall be calculated on the assl)ffiption that the Average Values set forth in Section 5.3(b)(3) below shall be achieved with respect to existing present claims and projected future claims involving Disease Levels II-VIII. The Payment Percentage may thereafter be adjusted upwards or downwards from time to time by the PI Trust with the consent ofthe T AC and the Futures Representative to reflect thencurrent estimates of the PI Trust's assets and its liabilities,_ as well as then-estimated value of then-pending and future claims. Any adjustment to the Initial Payment Percentage shall be made only pursuant to Section 4.2 below. If the Payment Percentage is increased over time, claimants whose claims were liquidated and paid in prior periods under the TDP shall receive additional payments only as provided in Section 4.2 below. Because there is uncertainty in the prediction of both the number and severity of future PI Trust Claims, and the amount of the PI Trust's assets, no guarantee can be made of any Payment Percentage of a PI Trust Claim's liquidated value. 2.4 PI Trust's Determination of the Maximum Annu~l Payment and Maximum Available Payment. The PI Trust shall estimate or model the arnollllt of cash flow anticipated to be necessary over its entire life to ensure that funds shall be available to treat all present and 6 JA 200296

future holders of PI Trust Claims as similarly as possible. In each year, the PI Trust shall be.empowered to pay out all of the income eamed during the year (net of taxes payable with respect thereto), together with a portion of its principal, calculated so that the application of PI Trust funds over its life shall correspond with the needs created by the estimated initial backlog of claims and the estimated anticipated future flow of claims (the "Maximum Annual Payment"), taking into account the Payment Percentage provisions set forth in Section 2.3 above and Sections 4.2 and 4.3 below. The PI Trust's distributions to all claimants for that year shall not exceed the Maximum Annual Payment determined for that year. In distributing the Maximum Annual Payment, the PI Trust shall first allocate the amount in question to (a) outstanding Pre-Petition Liquidated Claims; (b) PI Trust Claims involving Disease Level I (Cash Discount Payment) which have been liquidated by the PI Trust; (c) any PI Trust Claims based on a diagno_sis dated prior to the Effective Datt;: ("Existing Claims"); and (d) Exigent Hardship Claims (as defined in Section 5.4(b) below). Should the Maximum Annual Payment be insufficient to pay all such.claims in full, they shall be paid in proportion to the ~gregate value of each group of claims and the available funds allocated to each group of claims shall be paid to.the maximum extent to claimants in the particular group based on their place in their respective FIFO Payment Queue. Claims in any group for which there are insufficient funds shall be carried over to the next year, and placed at the head of their FIFO Payment Queue. The remaining portion of the Maximum ~ual Payment (the "Ma~imum Available Payment"), if any, shall then be allocated and used to satisfy all other liquidated PI Trust Claims, subject to the Claims Payment Ratio set forth in Section ~.5 below. Claims in the groups described in (a), (b), (c) and (d) above shall not be subject to the Claims Payment Ratio. 7 JA 200297

2.5 Claims Payment Ratio. Based upon Grace's claims settlement histories and analysis of present and future claims, a Claims Payment Ratio has been determined which, as of the Effective Date, has been set at 88% for Category A claims, which consist of PI Trust Claims involving severe asbestosis, severe disabling pleural disease and malignancies (Disease Levels IV-VIII) and at 12% for Category B claims, which are PI Trust Claims involving non-malignant Asbestosis or Pleural Disease (Disease Levels II and Ill). In each year, after the determination of the Maximwn Available Payment described in Section 2.4 above, 88% of that amount shall be available to pay Category A claims and 12% shall be available to pay Category B claims that have been liquidated since the Petition Date except for claims which, pursuant to Section 2.4 above, are not subject to the Claims Payment Ratio; provided, however, that the amount available to pay each Category of claims in each year.shall be proportionately reduced by the amounts required to pay any Insurance-Related TOP Claims {as defined in Section 5.12 below), any Indemnified Insurer TDP Claims (as defmed in. Section 5.13 below), and any BNSF TDP Claims (as defined in Section 5.14 below). In the event there are insufficient funds in any year to pay the liquidated claims within either or both of the Categories, the available funds allocated to the particular Category shall be paid to the maximwn extent to claimants in that Category based on their place in the FIFO Payment Queue described in Section S.I(c) below, which shall be based upon the date of claim liquidation. Claims for which there <!Ie insufficient funds allocated to the relevant Category shall be earned over to the next year where they shall be placed at the head of the FIFO Payment Queue. If there are excess funds in either or both Categories, because there is an insufficient amowlt of liquidated claims to exhaust the respective Maximwn Available Payment amount for that 8 JA 200298

Category, then the excess funds for either or both Categories shall be rolled over and remain dedicated to the respective Category to which they were origuial!y allocated. The 88%/12% Claims Payment Ratio and its rollover provision shall apply to all PI Trust Voting Claims as defined in Section 2.3 above (except Pre~ Petition Liquidated Claims, Other Asbestos Disease claims (Disease Level I - Cash Discowtt P ayment), Existing Claims and Exigent Hardship Claims), and shall not be amended until the third anniversary of the date the PI Trust first accepts for pro'cessing proof of claim forms and other materials required to file a claim with the PI Trust Thereafter, both the Claims Payment Ratio and its rollover provision shall be continued absent circumstances, such as a significant change in law or medicine, necessitating amendment to avoid a m~ifest injustice. However, the accumulation, rollover and subsequent delay of claims resulting from the application of the Claims Payment Ratio shall not, in and of itself, constitute. s~ch circumstances. In addition, an increase in the numbers of Category B claims beyond those predicted or expected shall not be considered as a factor.in deciding whether to reduce the percentage allocated to Category A claims. In considering whether to make any amendments to the Claims Payment Ratio and/or its rollover provisi?ns, the Trustees shall consider the reasons for which the Claims Payment Ratio and its rollover provisions were adopted, the settlement histories that gave rise to its calculation, and the foreseeability or lack of foreseeability of the reasons why there would be any need to make an amendment. In that regard, the Trustees should keep in mind the interplay between the Payment Percentage and the Claims Payment Ratio as it affects the net cash actually paid to claimants. In any event, no amendment to the Claims Payment Ratio to reduce the percentage allocated to Category A claims may be made without the Wianimous consent of the T AC 9 JA200299

members and the consent of the Futures Representative, and the percentage allocated to Category A claims may not be increased without the consent of the TAC and the Future& Representative. The consent process set forth in Sections 5, 7(b) and 6.6(b) of the PI Trust Agreement shall apply in the event of any amendments to the Claims Payment Ratio. The Trustees, with the consent of the T AC and the Futures Representative, may offer the option of a reduced Payment Percentage to holders of claims in either Category A or Category B in return for prompter payment (the "Reduced Payment Option"). 2.6 Indirect PI Trust Claims. As set forth in Section 5.6 below, Indirect PI Trust Claims, if any, shall be subject to the same categorization, evaluation, and payment provisions of this TDP as all other PI Trust Claims. SECTION3 TDP Administration 3.1 Trust Advisory Committee and Futures Representative. Pursuant to the Pll~J!- and the-pi Trust Agreement, the PI Trust and this TDP shall be administered by the Tn.tStees in consultation with the TAC, which represents the interests of holders of present PI Trust Claims, and the Futures Representative, who represents the interests of holders of PI Trust Claims that shall be asserted in the future. The Trustees shall obtain the consent of the T AC and the Futures Representative on any amendments to this TOP pursuant to Section 8.1 below, and on such other matters as are otherwise required below and in Section 2.2(f) of the PI Trust Agreement The Trustees shall also consult with the TAC and the Futures Representative on such matters as are. provided below and in Section 2.2(e) of the PI Trust Agreement. The initial Trustees, the initial members of the TAC and the initial Futures Representative are identified in the PI Trust Agreement. 10 JA 200300

3.2 Consent and Consultation Procedures.. fn those circumstances in which consultation or consent is required, the Trustees shall provide written notice to the T AC and the Futures Representative ofthe specific amendment or other action that is proposed. The Trustees shall not implement such amendment nor take such action unless and until the parties have engaged in the Consultation Process described in Sections 5.7(a) and 6.6(a), or the Consent Process described in Sections 5.7(b) and 6.6(b), of the PI Trust Agreement, respectively. SECTION 4 Payment Percentage; Periodic Estimates 4.1 Uncertainty of Grace's Personal Injury Asbestos Liabilities. As discussed above, there is inherent uncertainty regarding Grace's total asbestos-related tort liabilities, as well as the total value of the assets available to the PI Trust to pay PI Trust Claims. Consequently, there is inherent uncertainty regarding the amounts that holders of PI Trust Claims shall receive. To seek to ensure substantially equivalent treatment of all present and future PI Trust Claims, the Trustees must determine from time to time the percentage of full liquidated value that holders of present and future PI Trust Claims shall be likely to receive; i.e., the "Payment Percentage" described in Section 2.3 above and Section 4.2 below. 4.2 Computation of Payment Percentage. As provided in Section 2.3 above, the Initial Payment Percentage shall be set by t)le Trustees after consultation with the T AC and the Futures Repre~entative promptly after the date the PI Trust is established. The Initial Payment Percentage shaji be between 2~% and 35% and shall apply to all PI Trust Vo~ng Claims as defined in Section 2.3 above, unless the Trustees, with the consent of the TAC and the Futures Representative, determine that the Initial Payment Percentage should be changed to assure that the PI Trust shall be in a financial position to pay holders of unliquidated and/or unpaid PI Trust Voting Claims and present and future PI Trust Claims in substantially the same marmer. II JA 200301

In making any such adjustment, the Trustees, the T AC and the Futures Representative shall take into account the fact that the holders of PI Trust Voting Claims voted on the Plan relying on the findings of experts that the Initial Payment Percentage range represented a reasonably reliable estimate of the PI Trust's total assets and liabilities over its life based on the best information available at the time, and shall thus give due consideration to the expectations of PI Trust Voting Claimants that the Initial Payment Percentage would be applied to their PI Trust Claims. Except with respect to PI Trust Voting Claims to which the Initial Payment Percentage applies, the Payment Percentage shall be subject to change pursuant to the terms of this TDP and the PI Trust Agreement if the Trustees With the consent of the TAC and Futures Representative determine that an adjustment is required. No less frequently than once every three (3) years, commencing with the first day of January. occurring after the Effective Date, the Trusteel? shall reconsider the then applicable Payment Percentage to assure that it is based on accurate, current information and may, after such reconsideration, change the Payment Percentage if necessary with the consent ofthe TAC and the Futures Representative. The Trustees shall also reconsider the then applicable Payment Percentage at shorter intervals if they deem such reconsideration to be appropriate or if requested to do so by the TAC or the Futures Representative. The Trustees must base their determination of the Payment Percentage on current estimates of the number, types, imd values of present and future PI Trust Claims, the value of the assets then available to the PI Trust for their payment, all anticipated administrative and legal expenses, and any other material matters that are reasonably likely to affect the sufficiency of funds to pay a comparable percentage offull value to all holders of PI Trust Claims. When making these determinations, the Trustees shall exercise common sense and flexibly evaluate all 12 JA200302

relevant factors. The Payment Percentage applicable to Category A or Category B claims may not be reduced to alleviate delays in payments of claims in the other Category; both Categories of claims shall receive the same Payment Percentage, but the payment may be deferred as needed, and a Reduced Payment Option may be instituted as described in Section 2.5 above. 4.3 Applicability of the Payment Percentage. Except as set forth below in this Section 4.3 with respect to supplemental payments, no holder of a PI Trust Voting Claim, other than a PI Trust Voting Claim for Other Asbestos Disease (Disease Level I- Cash Discount Payment) as de:5ned in Section 5.3(a)(3) below, shall receive a payment that exceeds the Initial Payment Percentage times the liquidated value of the claim. Except as otherwise provided in Section 5.1 (c) below for Pl Trust Claims involving deceased or incompetent claimants for which approval of the PI Trust's offer by a court or through a probate process is required, no holder of any other PI Trust Claim, other than a PI TruSt Claim for Other Asbestos Disease (Disease Level I- Cash Discount Payment), shall receive a payment that exceeds the liquidated value of the claim times the Payment Percentage in effect at the time of payment. PI Trust Claims involving Other Asbestos Disease (Disease Level I- Cash Discount Payment) shall not be subject to the Payment Percentage, but shall instead be paid the full amount of their Scheduled Value as set forth in Section 5.3(a)(3) below. If a redetennination of the Payment Percentage has been proposed in writing by the Trustees to the T AC and the Futures Representative but bas not yet been adopted, the claimant shall receive the lower of the current Payment Percentage or the proposed Payment Percentage. However, if the proposed Payment Percentage was the lower amopnt but was not subsequently adopted, the claimant shall thereafter receive the difference between the lower proposed amount and the higher current amount. Conversely, if the proposed Payment Percentage was the higher 13 JA 200303

amount and was subsequently adopted, the claimant shall thereafter receive the difference between the lower current amount and the higher adopted amount. There is uncertainty surrounding the amount of the PI Trust's future assets. There is also uncertainty surrounding the totality of the PI Trust Claims to be paid over time, as well as the exte1,1t to which changes in existing federal and state Jaw could affect the PI Trust's liabilities ].lllder this TDP. If the value of the PI Trust's future assets increases significantly and/or if the value or volume of PI Trust Claims actually filed with the PI Trust is significantly lower than originally estimated, the PI Trust shall use those proceeds and/or claims savings, as the case may be, first to maintain the Payment Percentage then in effect. If the Trustees, with the consent of the TAC and the Futures Representative, make a determination to increase the Payment Percentage due to a material change in the estimates of the PI Trust's future assets and/or liabilities, the Trustees shall also make suppl~rp.ental payments to all claimants who previously liquidated their claims against the PI Trust and received payments based on a lower PaYlllent Percentage. The amount of any such supplemental payment shall be the liquidated value ofthe claim in question times the newly adjusted Payment Percentage, less all amounts previously paid to the claimant with respect to the claim (excluding the portion of such previously paid amounts that was attributable to any sequencing adjustment pai4 pursuant to Section 7.5 below). The Trustees' obligation to make a supplemental payment to a claimant shall be suspended in the event the payment in question would be less than $100.00, and the amount of the suspended payment shall be added to the amount of any prior supplemental payment/payments that was/were also suspended because it/they would have been less than 14 JA 200304

$100.00. However, the Trustees' obligation shall resume and the Trustees shall pay any such aggregate supplemental payments due the claimant at such time that the total exceeds $100.00. SECTIONS Resolution of PI Trust Claims. 5.1 Ordering, Processing and Payment of Claims. S.l(a) Ordering of Claims. S.l(a)(l) Establishment of the FIFO Processing Queue. The PI Trust shall order claims that are sufficiently complete to be reviewed for processing purposes on a FIFO basis except as otherwise provided herein (the "FIFO Processing Queue"). For all claims filed on or before the date six (6) months after the date that the PI Trust first makes available the proof of claim fonns and other claims materials required to file a claim with the PI Trust (such six month anniversary being referred to herein as the "Initial Claims Filing Date"), a claimant's position in the FIFO Processing Queue shall be detennined as of the earliest of (i) the date prior to April2, 2001 (the "Petition Date'') that the specific claim was either filed against Grace in the tort system or was actually submitted to Grace pursuant to an administrative settlement agreement; (ii) the date before the Petition Date that the asbestos claim was filed against another defendant in the tort system if at the time the claim was subject to a tolling agreement with Grace; provided, however, that if a claimant was barred from pursuing other defendants in the tort system by the terms of a preliminary injunction or other stay entered by the Court in the Grace bankruptcy proceedings and such claimant files an asbestos claim against another defendant in the tort system within one year after such preliminary: injunction or o1her stay is lifted, the claimant shall be deemed to have filed the asbestos claim against the other defendant on the date the preliminary injunction or other stay was first entered; (iii) the date after the Petition Date but before the date that the PI Trust first makes available the proof of claim.fonns 15 JA200305

and other claims materials required to file a claim with the PI Trust that the asbestos claim was filed against another defendant in the tort system; (iv) the date after the Petition Date but before the Effective Date that a proof of claim was filed by the claimant against Grace in the Chapter II Cases; or (v) the date a ballot was submitted on behalf of the claimant for purposes of voting to accept or reject the Plan pursuant to the voting procedures approved by the Bankruptcy Court. Following the Initial Claims Filing Date, the claimant's position in the FIFO Processing Queue shall be determined by the date the claim is filed with the PI Trust. If any claims are filed on the same date, the claimant's position in the FIFO Processing Queue shall be determined by the date of the diagnosis of the asbestos-related disease.

If the offer is ultimately approved by the court or through the probate process and accepted by the claimant's representative, the PI Trust shall pay the claim in the amount so offered, multiplied by the Payment Percentage in effect at the time the offer was first made. If any claims are liquidated on the same date, the claimant's position in the FIFO Payment Queue shall be detennined by the date of the diagnosis of the claimant's asbestosrelated disease.

Pre-Petition Liquidated Claims shall be processed and paid in accordance with their order in a separate FIFO queue to be established by the PI Trust based on the date the PI Trust received all required.documentation for the particular claim.. If any Pre-Petition Liquidated Claims were filed on the same date, the claimants' position in the FIFO queue for.such claims shall be detennined by the date on which the claim was liquidated. If any Pre-Petition Liquidated Claims were both filed and liquidated on the same dates, the position of the claimants in the FIFO queue shall be determined by the dates of the claimants' birth, with older claimants given priority over younger claimants. 5.2(b) Marshalling of Security. Holders of Pre-Petition Liquidated Claims that are secured by any Security shall first exhaust their rights against such Security before making a claim against the PI Trust.

Within six (6) months after the establislunent of the PI Trust, the Trustees, with the consent of the TAC and the Futures Representative, shall adopt procedures for reviewing and liquidating all unliquidated PI Trust Claims, which shall include deadlines for processing such claims. Such procedures shall also require that claimants seeking resolution of unliquidated PI Trust Claims must first file a proof of claim form, together with the required supporting documentation, in accordance with the provisions of Sections 6.1 and 6.2 below. It is anticipated that the PI Trust shall provide an initial response to the claimant within six (6) months of receiving the proof of claim form. The proof of claim form shall require the claimant to assert his or her claim for the highest Disease Level for which the claim qualifies at the time of filing. Irrespective of the Disease Level alleged on the proof of claim form, all claims shall be deemed to be a claim for the nighest Disease Level for which the claim qualifies at the time of filing, and all lower Disease Levels for which the claim may also qualify at the time of filing or in the future shall be treated as subsumed into the higher Disease Level for both processing and payment purposes. A claimant who has received payment for a Disease Level IV-A claim or a Disease Level IV-B claim may not assert or receive payment for another Disease Level IV claim. Upon filing of a valid proof of claim form with the required supporting documentation, the claimant shall be placed in the FIFO Processing Queue in accordance with the ordering criteria described in Section 5.l(a) above. The PI Trust shall provide the claimant with six (6) months notice of the date by which it expects to reach the claim in the FIFO Processing Queue, 21 JA200311

fouowing which the claimant shall promptly (i) advise the PI Trust whether the claim should be liquidated under the PI Trust's Expedited Review Process described in Section 5.3(a) below or, in certain circumstances, WJder the PI Trust's Individual Review Process described in Section 5.3(b) below; (ii) provide the PI Trust with any additional medical and/or exposure evidence that was not provided with the original claim submission; and (iii) advise the PI Trust of any change in the claimant's Disease Level. If a claimant fails to respond to the PI Trust's notice prior to the reaching of the claim in the FIFO Processing Que1,1e, the PI Trust shall process and liquidate the claim WJder the Expedited Review Process based upon the medical/exposure evidence previously submitted by the claimant, although the claimant shall retain the right to request Individual Review as described in Section 5.3(b) below. 5.3(a) Expedited Review Process. 5.3(a)(l) In General. The PI Trust's Expedited Review Process is designed prima,rily to provide an expeditious, efficient and inexpensive method for liquidating ~I PI Trust Claims (except those involving Lung Cancer 2- Disease Level VI and all Foreign Claims (as defined J>eiow), which shall only be liquidated pursuant to the PI Trust's Individual Review Process), where. the claim can easily be verified by the PI Trust as meeting the presumptive Medical/Exposure Criteria for the relevant Disease Level. Expedited Review thus provides claimants with a substantially less burdensome process for pursuing PI Trust Claims than does the Individual ReView Process described in Section 5.3(b) below. Expedited Review is also intended to provide qualifying claimants a fixed and certain claims payment. Thus, claims that WJdergo Expedited Review and meet the presumptive Medical/Exposure Criteria for the relevant Disease Level shait be paid the Scheduled Value for such Disease Level set forth in Section 5.3(a)(3) below. However, except for claims involving 22 JA 200312

Other Asbestos Disease (Disease Level I), all claims liquidated by Expedited Review shall be subject to the applicable Payment Percentage, the Maximum Available Payment, and the Claims Payment Ratio limitations set forth above; provided, however, that Existing Claims shall not be subject to the Maximum Available Payment or the Claims Payment Ratio. Claimants holding claims that cannot be liquidated by Expedited Review because they do not meet the presumptive Medical/Exposure Criteria for the relevant Disease Level may elect the PI Trust's Individual Review Process set forth in Section 5.3(b) belo.w. Subject to the provisions of Section 5.8, the claimant's eligibility to receive the Scheduled Value for hls or her PI Trust Claim pursuant to the Expedited Review Process shall be determined solely by reference to the Medical/Exposure Criteria set forth below for each of the Disease Levels eligible for Expedited Review. 5.3(a)(2) Claims Processing Under Expedited Review. All claimants seeking liquidation of their claims pursuant to Expedited Review shall file the PI Trust's proof (!f claim form. As a proof of claim form is reached in the FIFO Processing Queue, the PI Trust shall determine whether the claim described therein meets the Medical/Exposure Criteria for one of the seven Disease Levels.eligible for Expedited Review, and shall advise the claimant of its determination. If a Disease Level is determined, the PI Trust shall tender to the claimant an offer of payment of the Scheduled Value for the relevant Disease Level multiplied by the applicable Payment Percentage, together with a form of release approved by the PI Trust. If the claimant accepts the Scheduled Value and returns the release properly executed, the claim shall be placed in the FIFO Payment Queue, following which the PI Trust shall disburse payment subject to the limitations of the Maximwn Available Payment and Claims Payment Ratio, if any. 23 JA200313
